libjc is a framework for event-driven development in C. Programs that use it can perform an arbitrary number of operations simultaneously and in the background, and later wait for some or all of them to complete. The source package includes the core library along with a few objects, each of which is able to perform a set of related operations. This framework consumes significantly less memory than standard libraries, and it scales well to multiprocessor systems.
nioReactor is a framework for quickly building scalable event-driven network applications. It is built on top of the Reactor design pattern using NIO sockets. This provides high performance and allows for a complete separation from the application specific code. The goal of the project is to provide a simple set of APIs that allow users to build scalable servers without needing to deal with with the cumbersome and sometimes temperamental peaces of the NIO package.
